Abstract
Batting practice apparatus for projecting balls upwardly into the air to be hit by a bat comprises trough for holding a plurality of balls to move in a sequence toward a feed position adjacent a stop at a lower end. A holding ring is mounted adjacent the stop for supporting a single ball in a ready position to be projected upwardly into the air. A feeder is provided for sequentially moving the balls from a feed position in the trough adjacent the stop into a ready position in the holding ring and a motor in the form of a foot operated lever and a time delay mechanism is operable for forcefully propelling the balls upwardly out of the holding ring so that a batter may step into position and swing at the balls as they pop-up into the air.
